Assume that you are checking the continuity of cable pairs, using the
VF method. The preferred method uses a
headset and a buzzer.
buzzer and a decibel meter.
When station personnel install in-house cabling to terminal blocks on
distributing frames, they should perform tests to verify continuity.
The best time to do this is
at the time of forming the cable.
after all wires have been soldered to terminals.
when heat coils have been removed from protectors.
immediately upon soldering wire pairs to terminals.
During the cable-forming process, a technician fans out skinners to
appropriate terminal blocks on the distributing frame. The first step
in preparing the skinners is to
split the wire pairs.
remove a portion of the sheath.
lace and form the separated wire pairs.
remove the insulation from individual wires.
You should always use long-nosed pliers rather than diagonal-cutting
pliers to remove insulation from skinners, because long-nosed pliers
less likely to nick the wire.
less likely to draw heat from the joint.

more convenient in breaking off the excess wire after soldering.
